 Image Credit: NASA, JPL, Caltech Explanation: Why is 'Oumuamua differing from its expected trajectory? Last year, 1I/2017 U1 'Oumuamua became the first known asteroid from interstellar space to pass through our Solar System. Just over a year ago, this tumbling interstellar rock even passed rather close to the Earth. The asteroid's future path should have been easy to predict given standard gravity

Venus and the Triple Ultraviolet Sun Image Credit: NASA/SDO & the AIA, EVE, and HMI teams; Digital Composition: Peter L. Dove (http://www.flickr.com/photos/pldove/) Explanation: An unusual type of solar eclipse occurred in 2012. Usually, it is the Earth's Moon that eclipses the Sun. That year, most unusually, the planet Venus took a turn. Like a solar

THE ORIONID meteor shower promises to dazzle stargazers with a spectacular display of shooting stars TONIGHT. But what is the best time too watch the meteor shower?

Orionid Meteors Over Turkey  Credit & Copyright: Tunc TezelExplanation: Meteors have been flowing out from the constellation Orion. This was expected, as mid-October is the time of year for the Orionids Meteor Shower. Pictured above, over a dozen meteors were caught in successively added exposures over three hours taken this past weekend from a town near Bursa, Turkey. The

Dark Molecular Cloud Barnard 68  Image Credit: FORS Team, 8.2-meter VLT Antu, ESOExplanation: Where did all the stars go? What used to be considered a hole in the sky is now known to astronomers as a dark molecular cloud. Here, a high concentration of dust and molecular gas absorb practically all the visible light emitted from background stars. The eerily dark surroundings help

Eclipsosaurus Rex  Image Credit & Copyright: Fred Espenak (MrEclipse.com)Explanation: We live in an era where total solar eclipses are possible because at times the apparent size of the Moon can just cover the disk of the Sun. But the Moon is slowly moving away from planet Earth. Its distance is measured to increase about 1.5 inches (3.8 centimeters) per year due to tidal

Global Aurora at Mars  Image Credit: MAVEN, LASP, University of Colorado, NASAExplanation: A strong solar event last month triggered intense global aurora at Mars. Before (left) and during (right) the solar storm, these projections show the sudden increase in ultraviolet emission from martian aurora, more than 25 times brighter than auroral emission previously detected by the orbiting MAVEN spacecraft.
